I spent two nights on this hotel during my volcation (got five extra nights in Korea due to vulcanic ash) in Korea. Our group got booked to this hotel by staff from our initial hotel.
Rooms were spacious my room had two beds, a twin and a double (large enough for three persons). Bathroom was a bit shady. Floor heating made entire room too warm for a good sleep if one wants to sleep without air conditioning. Also noise from the streets comes in too loudly. Hotel did not offer breakfast, but you could walk into other hotels nearby to get some. Hotel offers free transportation from and to the airport.
Hotel is ok (it is relatively cheap) if you need to stay close to the airport and just need a roof over your head for a night or two. For longer stays I would recommend a hotel from Incheon downtown or Seoul.
Hotel is located in New Airport Town on a same island as the Incheon airport. Area is small and filled with a small hotels, restaurants, and bars. You can walk around all streets of this 'town' in an hour. There was a lot of construction work going on, so I guess the place is getting bigger. There is a train+underground connections to Incheon downtown (0,5 hour) and to Seoul (~2 hours).
